IJPJIP-COFFLE POT.

Application filed March 4, 1914.

To all whom it may concern:

Be it known that I, Eowann M. SWING, a citizen of the United States of America, residing at VVashington, District of Columbia, have invented certain new and useful. Improvements in Drip-Coffee Pots, of which the following is a specification.

This invention relates to improvements in cofi'ee pots and has particular reference to that class known as drip cofi'ee pots.

The present day method and use of pots employmg a bag or rag as a filtering me dium is decidedly objectionable, in that there is always present a slight rag flavor that ruins the fine quality of the finest of beverages.

The invention. has for its primary object the elimination of all the bad and faulty coffee making methods by the provision of a combination, construction and arrangement of parts which produce in their entirety a coffee pot which turns out coil'ee clear as Wine, golden, and the right flavor. in the least possible time and with the use of a minimum quantity of coffee. a The invention further contemplates the provision of a coffee pot of the character mentioned, wherein the different receptacles have no square edges, and perfectly smooth inner surfaces, thus eliminating all crevices and projections for the lodgment of coffee grounds, dirt or other foreign matter, thereby rendering the pot easy to clean as well as sanitary.'

Another object of the invention is the provision of a coffee pot of the class in question, which comprises comparatively few parts, simple in construction, cheap to manutao turc, and one highly eliicient for its purpose. Other objects of the invention will appear from the following description considered in connection with tin accompanying drawing.

in which lilccnumerals of reference indicate similar parts in the several views, and in which;

Figure l is a vertical sectional View through the invertible receptacle. Fig. 2 is a similar view through the outer vessel.

Fig. 3 is a sectional view through the pot with the parts assembled. F 1,2. 4 is a plan view of the perforated cover. 'Fig. is a detail section taken on line 5--:i of Fig. 1.

. The invention essentially consists of the vessel 5, an invertible receptacle indicated at (3, the perforated cap 7. and the filtering medium 8.

Specification of Letters Patent.

31%: tented New. 9, ifilifi'. Serial No. 822,261.

The vessel 5 constructed. in arcordance with the ordinary and well known form of cofl'ec or tea pot. and made from earthenare 0 any suitable material to permit of its use as a kettle for boiling the water for the coffee. The vessel is provided with suitable handle as at 9, the spout l0 and may he made of any desired capacity.

The receptacle is crmstructed as shown and preferably made from a single piece of any suitable material. The bodyportion of the receptacle is of slightly lesserdiaineter than the mouth of the vessel 5 and is adapt ed to snugly fit within the latter as shown in. Fig. The receptacle is provided with a circumferential head ill which rests zgainst the upper edge of the vessel 5 to support the former in inverted position within the latter. 3.. suitable handle projects outwardly from the body portion of the receptacle ll below the head 11. to facilitate the operative association of the receptacle with the vessel,

and their separatiim during the act of male ing colfee. Asshown in this particular 11- stance. the handle con'iprises a short socket member 13 in wl; :h is snugly fitted the removable handle ll which adapted to he removed for sl ipping purposes.

The receptacle may be of any desired ca parity and has its body portion from a point adjacent its upper edge'inclined inwardly to provide a reduced neck portion 15, which terminates in an outwardly extended circuniferential flange 16 forming a seat for the perforated cover 7 to, be hereinafter more fully described. The llang'e'lll is formed to provide a vertical flange 17 which embraces the walls of the cover 7. By reason of this particular construction. together with the fact that the bottom of the receptacle is con cave having: rounded edges, the receptacle is provided with a perfectly smooth interior, free from all crevices and projections in which the cotl'ee. grounds, dirt and other foreign matter would collect, thus rendering the pot extremely easy to clean as well sanitary.

The cover comprises a perforated hot permits the cover to be seated upon the flange 16 and by slightly turning the cover to the right the same will be locked in position, and vice versa.

In use, before the perforated cover 7 is locked in position, the filtering element 8 which comprises a single sheet of rice paper is laid across the top-of the receptacle. Obviously when the cover is locked in position on the receptacle the filtering element is effectively clamped therebetween, and the fianges 16 and 17 of the receptacle. The reason I specifically state that-the filtering element is in the nature of rice paper, is because experience has taught that this is the only filtering medium which relieves the beverage of that disagreeable rag taste noticeable in coffee which percolates through a bag or cloth.

It is a well known fact that the only correct method of making good coffee is to have everything connected therewith sufficiently heated, and by reason of this fact I boil the water for the coffee in the vessel 5 thus heating the latter to asufiioiently high degree. The pulverized coffee is then placed in the receptacle ('3, followed immediately by the boiling water. The rice paper is next laid across the top of the receptacle and finally the perforatedcover is locked in position, thus clamping the paper or filtering medium in the manner hereinabove described. Af'ter being allowed to stand a short while, the receptacle (3 is inverted and supported in the vessel 5, in the manner shown in Fig. 3. The coffee then percolates into the vessel 5, after which it is ready to be served. To speed this latter operation I employ an air valve 23 of any suitable construction. In one embodiment of the invention I have shown the valve as consisting of a hollow stem 24 threadedlyadjustable through a central aperture in the bottom'of the receptacle. The stem is slotted at one side as at 25 so that whenthe latter is partly moved from the aperture air isadmitted into the receptacle as will be readily understood.

A wine glass of coffee made in my pot and held up in front of the light reveals a liquor absolutely free from any sediment, cloudiness or grounds and with the full strength and flavor of the coffee in 1t.

Directions for coffee pots of the present I now consider the best embodiment of my I invention I desire to have it understood that the same is merely illustrative, and that various changes in the construction, proportion and the like may be resorted to whenv desired as fall within the scope of the appended claim.

Having thus described the invention,what I claim is:

An invertible percolating receptacle for coffee pots comprising a body of uniform diameter throughout the major portion of its length and having a reduced neck portion terminating in an outwardly extending circumferential flange, a vertical flange rising from the lateral flange in a plane with the body portion of the receptacle, a flexible filtering element adapted to be laid across the open end ofthe receptacle, a cup-shaped cover for clamping said element in position therebetween and said flanges, and a valve in the opposite end of the receptacle.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.
